Here's another one. My EGT's have been slowly getting higher. I use to see 300 at idle, easily. Now I'm up to almost 400 and it's colder outside now. I'm seeing upwards of 900 when accelerating to only 45-50 mph at no more than 2000 RPM. Also, I've noticed soot on the firewall, behind the turbo and I don't see more than 10-12 pounds of boost when getting into it moderately hard. I see 3 pounds when cruising at 60 MPH. As far as the boost, that's how it's been since I got it, but now I'm thinking it's low for the mods the truck has. Although, the turbo sounds what I think to be normal. Does all this sound to be related or separate issues?

My temp gauge is working and cycles as it should and the heat is working well. I know the truck has the upgraded 203 thermostat. So, I don't think the EGT's are related to a coolant system issue. Whatcha think?

It's a little hard to tell from the pic, but from what I can see it looks like you've got a hole rusted through on the exhaust side of the turbo? Never seen that one before...
Generally its "just" a matter of replacing the gasket. This is still a huge PITA. In order to get enough room to work, you either have to remove the turbo or drop the transmission.
You can also replace the entire up-pipe with a bellowed one that eliminates the gasket, but that will cost you some serious coin.

How old is that turbo? I see you're running a D66, so I assume it's relatively new.

Bought it like this. Everything was already installed, don't know how long ago though. The housing is pretty rusted, I'm afraid the bolts are just gonna snap off when I try to take the thing apart. I guess we'll find out.

Yeah finding a new exhaust housing shouldn't be too hard. They aren't typically a high fatigue item, so check out the local junk yard.
PB-Blaster is your friend. Heating/cooling cycles have a tendency to make any exhaust or turbo bolt fairly hard to get out.
